Add move/transfer assets

Add ability to move / transfer assets between clients. Moving an asset involves the asset being archived and then re-created under the new client with most of the same information.

Information about the old & new asset is stored in the audit logs and within the asset notes. Information from the audit logs is accessible via a new History tab on the asset, subject to audit log retention.
